Course Goals

Course Objectives

Course Outcomes

Course Assessment: The assessment of objectives is achieved through homework assignments and common examinations with common grading. Homework assignments chosen from the text are listed below. Students are required to work through these problems after each lecture in order to gain a better understanding of the course material. Seven or eight additional problem sets will be assigned during the course of the semester. These are an extremely important component of the homework grade.

Policies

DMS Course Policies: All DMS students must familiarize themselves with, and adhere to, the Department of Mathematical Sciences Course Policies, in addition to official university-wide policies. DMS takes these policies very seriously and enforces them strictly.

Grading Policy: The final grade in this course will be determined as follows:

Homework, Quizzes, and MATLAB 17%
Common Midterm Exam I 17%
Common Midterm Exam II 17%
Common MIdterm Exam III 17%
Final Exam 32%

Your final letter grade will be based on the following tentative curve.

A 85 - 100 C 65 - 69
B+ 80 - 84 D 60 - 64
B 75 - 79 F 0 - 59
C+ 70 - 74

Attendance Policy: Attendance at all classes will be recorded and is mandatory. Please make sure you read and fully understand the Math Department’s Attendance Policy. This policy will be strictly enforced.

Exams: There will be three midterm exams held during the semester and one comprehensive final exam. Exams are held on the following days:

Common Midterm Exam I February 14, 2018
Common Midterm Exam II March 7, 2018
Common Midterm Exam III April 18, 2018
Final Exam May 4 - 10, 2018

The time of the midterm exams is 4:15 - 5:40PM for daytime students and 5:45 - 7:10PM for evening students. The final exam will test your knowledge of all the course material taught in the entire course. Make sure you read and fully understand the Math Department's Examination Policy. This policy will be strictly enforced.

Makeup Exam Policy: To properly report your absence from a midterm or final exam, please review and follow the required steps under the DMS Examination Policy found here:

Cellular Phones: All cellular phones and other electronic devices must be switched off during all class times.
